Description
ALS Interrupt Direct. If asserted, then the INT pin shows the ALS state
directly and it is not necessary to clear the interrupt. If the CLEAR data
7
exits the threshold range from within, the INT pin is asserted. The
interrupt pin is de-asserted when the CLEAR data re-enters the
threshold range. As long as the CLEAR data is within the thresholds,
the INT pin is not asserted.
ALS Interrupt Direct on GPIO Pin. If asserted, the GPIO pin shows
6 the ALS interrupt state directly instead of the INT pin. This function
operates in the same manner otherwise as ALS_INT_DIRECT.
Proximity Interrupt Direct. If asserted, then the INT pin shows the
proximity state directly and it is not necessary to clear the interrupt. If
5
PDATA crosses the upper threshold from below, the INT pin is
asserted. The interrupt pin is only de-asserted when PDATA crosses
the lower threshold from above. As long as PDATA is below the lower
threshold, the INT pin is not asserted.
Proximity Interrupt Direct on GPIO Pin. If asserted, the GPIO pin
4
shows the proximity interrupt state directly instead of the INT pin. This
function operates in the same manner otherwise as
PROX_INT_DIRECT.
3:0 Reserved.
